Grand Canyon West sits on Hualapai land: the west rim, Eagle Point, and overlooks you reach by helicopter from Las Vegas in about 45 minutes. This tour lands there. You then have about three hours on the ground to walk the viewpoints before the flight back.
The Skywalk at Eagle Point is optional and paid separately. The canyon you see from the air on the way in is the west rim, not the South Rim visitor-center view. This flight leaves the Las Vegas Strip terminal.
